Definitions

  • the invention relates to a method for charging a battery by rectangular current pulses alternately taking a first amplitude during a first period and a second amplitude, different from the first one, during a second period.
  • This method comprises determination of a first slope value representative of the variation of the voltage at the terminals of the battery versus time, from successive measurements of said voltage during each first period.
  • Charging or recharging a battery is conventionally performed under the control of a charge regulator.
  • the different ways of managing a battery charge currently used are based either on measurement of the voltage at the battery terminals or on measurement of the battery charging current.
  • a first known management mode is of the connection/disconnection (On/Off) type, based on interrupting charging when the voltage reaches a high threshold and resuming charging when the voltage reaches a reconnection voltage threshold.
  • this management mode which is easy to implement, the voltage thresholds are often badly adjusted and it is difficult to fully charge the battery.
  • Another known management mode consists in keeping the battery voltage constant, which enables the current value to be reduced when the required voltage is reached, possibly using pulse width modulation (PWM) of the charging current.
  • PWM pulse width modulation
  • a large power dissipation is required and the voltage thresholds are often badly adjusted.
  • a management mode based on current measurement uses counting of the ampere-hours input to and output from the battery. This management mode is fairly rarely used as it is imprecise in time and does not take account of degassing correctly, in particular in the case of open lead-acid batteries with a liquid electrolyte.
  • Another management mode developed in particular for batteries equipping electric vehicles, uses a pulsed charging current. This in particular enables the recharging time of the battery to be reduced, but the current parameters are often badly adjusted.
  • U.S. Pat. No. 6,154,011 proposes to modify the mean charging current of the battery according to the mean overvoltage so as to maintain an acceptable hydrolysis level.
  • the mean current charging means can be adapted by reducing the amplitude of the current pulses, by increasing the interval between two current pulses (OFF-time) and/or by reducing the duration (ON-time) of the charging current pulses.
  • U.S. Pat. No. 5,412,306 proposes to reduce the amplitude of a current pulse by a predetermined factor, for example to divide it by 2, so as to constitute a stepped-down pulse when the voltage slope versus time reaches zero after it has reached a certain value (for example 2.5 V/s). End of charging of the battery is thus not performed by pulsed current, but by a succession of stepped-down pulses each having decreasing amplitude steps.
  • Document EP-A-1341286 describes a battery charging method comprising a boost charge phase, an equalization charge phase and a maintenance charge phase.
  • the boost charge phase is completed when the voltage presents two inflection points of opposite signs.
  • the charging current can be a pulsed current.
  • charging is completed when the voltage at the battery terminals or the voltage gradient exceeds a threshold value.
  • the current can be zero until the voltage drops back below a voltage threshold and take a predetermined maximum value until the voltage or the voltage gradient reaches a predetermined threshold.
  • the object of the invention is to overcome the drawbacks of known charging methods and, more particularly, to enable the set of pulsed current charging parameters of any type of battery and for any type of application to be determined.
  • this object is achieved by a charging method according to the appended claims and, more particularly by the fact that, the first amplitude and the duration of the first period being previously determined, the method comprises servo-control of at least one of the current parameters during the subsequent first periods as a function of said first slope value, calculated and compared with a first predetermined range at the end of each first period, the first current amplitude and/or the duration of the first period being modified if the first slope value goes outside the first range.
  • FIG. 1 schematically illustrates the variations, versus time, of the charging current I of a battery charged by the method according to the invention, and the corresponding variations of the voltage U.
  • FIG. 2 illustrates the variations, versus time, of the voltage U at the terminals of the battery charged by the method according to the invention.
  • FIGS. 3 to 6 illustrate the variations, versus time, of the voltage U at the terminals of a battery, respectively when the duration of a first period t 1 is not suitable ( FIGS. 3 and 4 ) or when the duration of a second period t 2 is not suitable ( FIGS. 5 and 6 ).
  • FIGS. 7 to 10 represent flowcharts of a first embodiment of the method according to the invention.
  • FIGS. 11 to 14 represent flowcharts of a second embodiment of the method according to the invention.
  • FIGS. 15 and 16 represent the flowcharts of two other embodiments of a method according to the invention.
  • FIGS. 17 and 18 illustrate in greater detail the variations of the voltage measured when charging a battery, charged with pulses of constant amplitude, respectively before and after adjustment of the time parameters of the current pulses according to the invention.
  • FIGS. 19 and 20 illustrate in greater detail the variations of the voltage measured when charging a battery, charged with a pulsed current of constant mean amplitude, respectively before and after adjustment of the current pulse parameters according to the invention.
  • the charging current I of the battery is a pulsed current between times A and B, after application of a current of constant amplitude up to the time A.
  • the pulsed current be applied to the battery from the very beginning of charging or recharging.
  • the pulsed current is conventionally constituted by rectangular current pulses alternately taking a first amplitude I 1 , during a first period t 1 , and a second amplitude I 2 , lower than the first one, during a second period t 2 .
  • a first value of the slope P 1 of the voltage U, measured at the terminals of the battery to be charged, is calculated at least at the end of the first period t 1 .
  • At least one of the current parameters (I 1 , t 1 ) during the first period is automatically servo-controlled as a function of the first calculated slope value P 1 .
  • a second value of the slope P 2 of the voltage U, measured at the terminals of the battery to be charged is calculated at least at the end of the second period t 2 .
  • At least one of the current parameters (I 2 , t 2 ) during the second period is automatically servo-controlled as a function of the second calculated slope value P 2 .
  • the different parameters of the pulsed charge current are thus continuously servo-controlled as a function of the slope P of the voltage U measured at the battery terminals.
  • the absolute values of the first and second slope values P 1 and P 2 representative of the variation of the voltage U versus time, respectively at the end of the first and second periods (t 1 , t 2 ), are comprised between 1 mV/s and 6 mV/s. The evolution of the voltage U over time thus obtained is then optimal.
  • Charging the battery with a pulsed current which is servo-controlled as a function of the voltage slope enables the charge to be optimized according to the type of battery and the field of application of this battery. Charging is then performed in a minimum time, while regulating the hydrolysis efficiently for aqueous liquid electrolyte batteries and increasing the capacity and lifetime of the battery.
  • FIGS. 7 to 10 illustrate an example of flowcharts of a first embodiment of a method according to the invention, which can be implemented by any known type of charge regulator.
  • the charging parameters are initialized according to the technical characteristics of the battery to be charged and the field of application for which this battery is intended, which determine its operating conditions.

  • the voltage U at its terminals will have to be limited so as not to exceed a threshold, on average about 2.4V to 2.45V per electrochemical cell, so as to limit the damage liable to be caused by a large hydrolysis.
  • the amplitude I 2 can be zero.
  • the charge regulator goes on to a step F 2 of charging the battery with a current having a first amplitude I 1 so long as the first slope value P 1 remains outside a first range, preferably comprised between 1 mV/s and 6 mV/s.
  • Charging of the battery by the current pulse of amplitude I 1 is interrupted when the slope P 1 of the voltage U at the terminals of the battery enters the corresponding range.
  • the duration of the first period t 1 is thus servo-controlled as a function of the first slope value P 1 .
  • the regulator controls, in a step F 3 , charging of the battery with a current having a second amplitude I 2 , lower than the first amplitude I 1 , so long as the second slope value P 2 remains outside a second range, preferably identical to the first one, i.e. comprised, in absolute value, between 1 mV/s and 6 mV/s. Charging of the battery by the current pulse of amplitude I 2 is then interrupted when the slope P 2 enters the corresponding range, thus servo-controlling the duration of the second period t 2 as a function of the second slope value P 2 .
  • step F 4 the regulator checks, in a step F 4 (Stop?), whether the battery is sufficiently charged, i.e. whether the charge should be interrupted or not.
  • the decision criterion corresponding to stopping charging can be constituted by any criterion conventionally used when charging a battery. If this criterion is met (Yes output of F 4 ), the regulator goes on to an end of charging step F 5 . If not (No output of F 4 ), it loops back to the input of step F 2 and continues charging the battery by pulses alternately taking the first and second amplitude I 1 and I 2 , during first and second periods t 1 and t 2 , respectively servo-controlled as a function of the first and second slope values P 1 and P 2 .
  • steps F 1 to F 3 are illustrated in greater detail respectively in FIGS. 8 to 10 .
  • the initialization step F 1 first comprises, in a step F 6 , determination of the first and second amplitudes I 1 and I 2 of the charging current depending on the type of battery to be charged and the application for which this battery is intended.
  • the amplitudes I 1 and I 2 remain unchanged throughout charging, the parameters which are servo-controlled as a function of the slope P of the voltage U being the first and second periods t 1 and t 2 .
  • Step F 6 is followed by a step F 7 in which the value of the voltage U(t) is initially set to zero.
  • the regulator loops back to the step F 8 . It therefore continues to apply the current of amplitude I 1 , unchanged, to the battery and stores the previously measured voltage value before calculating a new value of P 1 .
  • the succession of steps F 8 to F 11 are repeated so long as the first slope value P 1 remains outside the first range and, throughout this first period, the successive measurements of the voltage U(t) are made at predetermined time intervals ⁇ t. These time intervals ⁇ t preferably have a much shorter duration than the first period t 1 .
  • step F 11 When, in step F 11 , the regulator ascertains that the first slope value P 1 has entered the first range (Yes output of F 11 ), step F 2 is stopped and the regulator then goes on to step F 3 .
  • step F 3 can, in the same way as step F 2 , begin by a step F 12 in which the amplitude of the charging current I is set to the value I 2 (previously determined during step F 6 ), the previously recorded value of the voltage being stored.
  • FIGS. 11 to 14 illustrate an example of flowcharts of a second embodiment of a method according to the invention.
  • a step F 16 illustrated in greater detail in FIG. 12 , the charging parameters are first of all initialized according to the technical characteristics of the battery to be charged and the field of application for which this battery is intended.
  • initial values of the parameters I 1 , I 2 , t 1 and t 2 are determined in the course of a step F 27 , followed by a step F 7 in which the value of the voltage U(t) is initially set to zero.
  • step F 16 after the initialization step F 16 , the charge regulator goes on to a step F 17 of charging the battery with a current having a first amplitude I 1 during a first period t 1 . Then, the regulator goes on to a step F 19 of charging the battery with a current having a second amplitude I 2 during a second period t 2 . At the same time, at the end of step F 17 , the regulator calculates the first slope value P 1 , in a step F 10 , and then compares the calculated first slope value with the first range in a step F 11 . If the first slope value P 1 is outside the first range (No output of F 11 ), the regulator modifies certain parameters in a step F 18 .
  • step F 19 the regulator calculates the second slope value P 2 , in a step F 14 , and then compares the calculated second slope value with the second range in a step F 15 . If the second slope value P 2 is outside the second range (No output of F 15 ), the regulator modifies certain parameters in a step F 20 . At the same time, at the output of step F 19 , as at the output of step F 3 of FIG. 7 , the regulator checks, in a step F 4 (Stop?) whether the battery is sufficiently charged. If this is the case (Yes output of F 4 ), the regulator goes on to an end of charging step F 5 .
  • step F 17 If not (No output of F 4 ), it loops back to the input of step F 17 and continues charging the battery by pulses alternately taking the first and second amplitude I 1 and I 2 , which may have been modified in F 18 or F 20 , during first and second periods t 1 and t 2 , which may have been modified in F 18 or F 20 .
  • steps F 17 and F 19 are illustrated in greater detail respectively in FIGS. 13 and 14 .
  • the regulator checks, in a step F 30 , whether the time elapsed since the beginning of the step F 17 is equal or not to the first period t 1 . If this is the case (Yes output of F 30 ), step F 17 is terminated. If not (No output of F 30 ), the regulator loops back to step F 8 and continues charging the battery with the pulse of amplitude I 1 until the end of the first period t 1 .
  • the regulator checks, in a step F 33 , whether the time elapsed since the beginning of step F 19 is equal or not to the second period t 2 . If this is the case (Yes output of F 33 ), step F 19 is terminated. If not (No output of F 33 ), the regulator loops back to step F 12 and continues charging the battery with the pulse of amplitude I 2 until the end of the second period t 2 .
  • Calculation of the new parameters in step F 18 is designed to servo-control the first current amplitude I 1 and/or the duration of the first period t 1 as a function of the first slope value P 1 calculated at the end of the first period t 1 .
  • the first slope value P 1 is, in absolute value, higher than the upper limit of the first range, for example greater than 6 mV/s, this means that the first period t 1 is too short, as in FIG. 4 , and/or that the first amplitude I 1 is too high.
  • Calculation of the new parameters in step F 18 then consists in increasing the first period t 1 and/or reducing the first amplitude I 1 , depending on the field of application of the battery and its operating conditions.
  • the first slope value P 1 is, in absolute value, lower than the lower limit of the first range, for example less than 1 mV/s, this means that the first period t 1 is too long, as in FIG.
  • step F 18 calculates the new parameters in step F 18 .
  • step F 18 then consists in reducing the first period t 1 and/or increasing the first amplitude I 1 , depending on the field of application of the battery and its operating conditions. In the latter case, for a photovoltaic installation for example, the current delivered by the solar panels depends on the sunshine and it is therefore preferable to make an adjustment to the duration of the period t 1 rather than the amplitude I 1 .
  • step F 20 calculation of the new parameters in step F 20 enables servo-control of the second current amplitude I 2 and/or the duration of the second period t 2 as a function of the second slope value P 2 , calculated at the end of the second period t 2 .
  • the mean value Imean of the charging current is then initially determined, at the same time as the values I 1 , I 2 , t 1 and t 2 , during the initialization step F 16 , according to the technical characteristics of the battery to be charged and the field of application for which this battery is intended.
  • a third embodiment, illustrated in FIG. 15 combines step F 2 of the first embodiment ( FIG. 7 ) during the first charging periods and steps F 19 , F 14 , F 15 and F 20 of the second embodiment ( FIG. 11 ) during the second charging periods.
  • an initialization step F 34 the values of I 1 , I 2 , t 2 , and if applicable Imean, are determined.
  • the regulator charges the battery with a current of amplitude I 1 so long as the first slope value P 1 remains outside the first range.
  • step F 19 it charges the battery with a current of amplitude I 2 during the second period t 2 , and then calculates P 2 (step F 14 ) and compares it with the second range (step F 15 ). If P 2 is outside the second range (No output of F 15 ), the regulator modifies I 2 and/or t 2 , while keeping the mean current value Imean constant if applicable. As in FIG. 11 , steps F 4 and F 5 follow step F 19 and the regulator loops back to step F 2 if charging is not completed (No output of F 4 ).

  • the battery is charged with a pulsed current taking a first amplitude I 1 of 2.5 A during a first period t 1 of 10 s and a zero second amplitude I 2 during a second period t 2 of 10 s.
  • FIG. 17 illustrates the voltage variations without adjustment of the time parameters of the current pulses according to the invention, for a charged state of 90%.
  • the slope values P 1 and P 2 at the end of the first and second periods are respectively equal to 0.9 mV/s and 0.2 mV/s, in absolute value. These two values are, in absolute value, lower than the lower limit of 1 mV/s of the corresponding first and second range. The durations of the first and second periods are therefore unsuitable.
  • FIG. 18 illustrates the voltage variations obtained after adjustment of the time parameters t 1 and t 2 according to the invention.
  • Servo-control of t 1 and t 2 as a function of the slope values P 1 and P 2 leads to a decrease of t 1 and t 2 to bring P 1 and P 2 into their respective ranges at the end of the first and second periods.
  • the optimum parameters obtained are 3 s for t 1 and 1.9 s for t 2 .

  • the first period t 1 is 15 s, for a charging current having a first amplitude I 1 of 2.5 A, whereas the second period t 2 is set to 5 s with a charging current having a zero second amplitude I 2 .
  • the absolute values of the slope values P 1 and P 2 at the end of the first and second periods are respectively equal to 0.6 mV/s and 1.3 mV/s.
  • the first slope value P 1 is therefore lower than the lower limit of 1 mV/s of the first range, whereas the absolute value of the second slope value P 2 at the end of the second period is within the limits of the second range.
  • the charging current parameters are therefore unsuitable.
  • FIG. 20 illustrates the voltage variations obtained after adjustment of the current parameters according to the invention.
  • Servo-control of I 1 and t 1 as a function of the first slope value P 1 leads to a decrease of t 1 and an increase of I 1 to bring P 1 into the first range at the end of the first period.
  • the optimum parameters obtained are 5.5 s for t 1 and 3.58 A for I 1 .
  • the first slope value P 1 at the end of the first period is then equal to 2.4 mV/s, whereas the absolute value of the second slope value P 2 at the end of the second period remains unchanged at 1.3 mV/s.
  • the charging method according to the invention therefore enables the set of parameters of the pulsed current to be continuously adjusted when charging or recharging any type of battery, for example for different types of lead-acid batteries, and for any type of application, in particular for batteries used in electric vehicles, in photovoltaic applications, etc.
  • the method applies equally well to recharging the battery in the course of use thereof and to the first charge of the battery when the latter is manufactured.
  • the first charge of a lead battery when the latter is manufactured in fact enables lead dioxide PbO 2 to be formed at the positive plates of the battery and lead Pb to be formed at the negative plates of the battery.
  • Lead and lead dioxide are however the two chemical species produced when charging of the battery is performed, whereas lead sulfate PbSO 4 appears when the battery discharges.
  • conventional manufacturing of a battery only leads to partial use, less than 50%, of the active material. Yet it has been shown, in an article by Diniz et al., in “Journal of Power Sources”, vol. 109, p.
  • servo-control of one of the current parameters as a function of the slope of the voltage U versus time can be limited to one of the first and second periods only.
  • servo-control of both the slope values P 1 and P 2 enables a better optimization
  • servo-control of one slope value only, P 1 or P 2 can be envisaged and already enables charging of the battery to be improved in comparison with known charging methods.
  • the slope value P 2 is negative, whereas the slope value P 1 is positive.
  • Preferential use of the absolute value when calculating the slope values means that the signs do not have to be taken into account when the slope values are compared with the ranges, which can themselves then be defined in absolute value only.
